Hello,
How to possible static dns entries as like
Name : myname.bd
to address : 192.168.1.5:9009 [address with port]
This is not possible on any DNS software.
At least you must buy a short.url/link and manage the redirect to https://myname.bd:9009/
What do people learn in networking classes these days?
It’s not completely impossible, there are SRV records that are meant to point services elsewhere, including different ports. Problem is, it’s application-specific. So for example XMPP can use it, because it’s standard part of protocol. But for web it won’t work, because AFAIK no browser supports it.
